{ split from #4 item 1}

Context

Evaluate the performance of hyper network connectivity within the same cloud. The targets are less than 30% impact vs. baseline (refer to #46 ).

Task

Compare performance of communication between 2 Hyper VMs in same subnet and on different subnets as follows:

Scenario	VM to VM (baseline)	HVM to HVM
Same Subnet
Different Subnets

Details

HVMs are deployed using the Agent + Container based on OpenStack Liberty DVR and LXC.

I have done a short test of the OVS performance on AWS. I have created 2 VMs of type t2.small (1Gbps interface), connected via a HyperNode of type c3.8xlarge(10Gbps interface). Attached is the result of running iPerf between the VMs

The first test is using the Hyper IPs (going through the HyperNode)
The second test is using the provider IPs (going directly between the VMs)

As you can see, we are getting similar results in both cases.

hi Shachar, I re-opened this issue. Issues here should be reviewed on weekly meeting before closed.

And I also think you need do some pressure tests to probe the performance limit of HyperNode, like, create 5-50 vms per subnet then repeat above test to check the performance degradation.
